The impact of socioeconomic status in hernia treatment: a qualitative systematic review.

Clinical Snapshot

Key Findings

• P Value: Not specified in abstract

• Effect Size: Increased odds ratios for adverse outcomes in Medicaid/Medicare patients (specific values not provided in abstract)

• Primary Outcome: Higher complication rates, readmissions, and recurrence in government-funded insurance patients

• Nnt Or Sensitivity: Government-funded insurance patients had consistently worse outcomes across multiple domains including wound complications and hospital readmissions

• Confidence Interval: Not specified in abstract

Clinical Application

Findings highlight need for systematic approaches to reduce healthcare disparities in surgical care While US-specific, similar disparities may exist in Australian healthcare despite Medicare coverage.

Abstract

INTRODUCTION: Hernias are among the most common surgical conditions worldwide. However, access to optimal treatment remains disproportionately distributed. Socioeconomic disparities play a critical role in determining whether patients receive timely surgical intervention, access to minimally invasive techniques, or suffer from postoperative complications due to delayed or suboptimal care. This study aims to evaluate the impact of socioeconomic disparities on the treatment of ventral hernia repair. METHODS: This systematic review was conducted following PRISMA guidelines. A comprehensive search was conducted using MEDLINE/Pubmed, EMBASE, Web of Science, Cochrane Library, and LILACS, from inception until March 2026 without any filter applied. A search strategy was created using the MeSH terms. Our inclusion criteria comprise studies related to socioeconomic disparities in ventral hernia repair within the United States. Due to heterogeneity in study designs, socioeconomic variables, and outcome definitions, a meta-analysis was not feasible, and findings were synthesized using a narrative synthesis. A qualitative assessment of included studies was made using the Cochrane Risk of Bias tool, ROBINS-I. RESULTS: A total of 28 studies were included, encompassing 2,096,513 patients with ventral hernia. Most were retrospective cohorts, with sample sizes ranging from a few hundred to over 665,000 patients. Across studies, patients with government funded insurance (Medicaid or Medicare) generally experienced higher rates of complications, readmissions, and recurrences compared to commercial insured patients, although the magnitude of association varied. Odds ratios demonstrated increased risks of wound complications, readmission, and recurrence among government funded insured and uninsured patients, while commercial insured and higher-income patients were more likely to undergo advanced surgical approaches and had shorter hospital length of stay. Some studies also highlighted socioeconomic and racial disparities, with vulnerable populations and minority groups showing disproportionately higher complication rates and different patterns of insurance coverage. CONCLUSION: This systematic study demonstrates significant racial and socioeconomic disparities in ventral hernia repair. Government funded insurance holders or lower incomers, faced higher complication rates, more emergent presentations, and worse outcomes, including increased mortality and readmissions. Moreover, they usually have less access to minimally invasive and robotic techniques. These inequities highlight systemic barriers in healthcare access.
